Abstract

PURPOSE:To improve the thermal equilibrium by detecting separately the axial vibration component in a rotor is heated from the outside and the axial vibration component in the rotor is heated from the inside thereof and adding vectorially by converting into the temperature state at the time of actual loading respectively. CONSTITUTION:A rotor has a rotor drum 1a and a rotor winding 1b to be wound and retrieved on the drum 1a, and a refrigerant channel 1c is provided to the inside of the rotor. The rotor 1 is supported by a bearing 2 so as to rotate and is rotated with specific motor speed by a driving motor 3 in case of balance controlling. A heater 5 for making the thermal control of the rotor 1 from the outer surface is provided to the internal clearance of a cover 4, and a device 6 for heating the rotor 1 from its inside is also provided. At the time of the rotation of the rotor 1, the axial vibration is detected by an axial vibration measuring device 8 through an axial vibration sensor 7. The axial vibration component is detected by heating respectively from the inside and the outside, then it is converted into the temperature state at the time of actual loading to be added.
